Error in Adobe Acrobat
Sometimes the error occurs in the reading order window that a tag is not created correctly. In the example below, an image was marked that does not yet have a tag in the tag structure tree.
After selecting the image and clicking on “Image” in the reading order window, a new element for the image is created in the order structure tree, but the new tag is missing in the tags structure tree.
solution in Adobe Acrobat
1. In the tab “Display” > “Show/Hide” > “Navigation window” > “Content” activate
2. Find the image container in the content tree > drag the image element out of the container
3. Right-click on the empty container > “Delete”
As soon as you create a new tag for the image in the reading order window, it will be displayed correctly in the tag structure tree.
